                        SCIENTIFIC GAMES HOLDINGS CORP.
              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

                                  (UNAUDITED)


Note 1.           Basis of Presentation

                  The accompanying unaudited consolidated condensed financial
         statements have been prepared in accordance with generally accepted
         accounting principles for interim financial information and with the
         instructions to Form 10-Q and Article 10 of Regulation S-X.
         Accordingly, they do not include all of the information and footnotes
         required by generally accepted accounting principles for complete
         financial statements and should be read in conjunction with the
         financial statement disclosures contained in the Company's 1999 Annual
         Report on Form 10-K for the year ended December 31, 1999. In the
         opinion of management, all adjustments considered necessary for a fair
         presentation (which were of a normal, recurring nature) have been
         included. Operating results for the three and six month periods ended
         June 30, 2000 are not necessarily indicative of the results that may
         be expected for the year ended December 31, 2000.

Note 2.           Inventories

                  Inventories consist principally of instant lottery tickets,
         materials related to their production and certain electronic
         components related to Systems terminals which are valued at the lower
         of cost (first-in, first-out method) or market. Inventories consisted
         of the following at:

Note 3.           Contingencies

                  As initially reported in July 1993 and periodically reported
         thereafter, the Company's Scientific Games Inc. ("SGI") subsidiary
         owns a minority interest in Wintech de Colombia S.A. ("Wintech"),
         which formerly operated the Colombian national lottery under contract
         with Empresa Colombiana de Recursos para la Salud, S.A. ("Ecosalud"),
         an agency of the Colombian government. The contract projected that


                                       7

Note 3.           Contingencies continued

         certain levels of lottery ticket sales would be attained and provided
         a penalty against Wintech, SGI and the other shareholders of Wintech
         of up to $5.0 million if such performance levels of lottery ticket
         sales were not achieved. In addition, with respect to a further
         guarantee of performance under the contract with Ecosalud, SGI
         delivered to Ecosalud a $4.0 million bond issued by a Colombian
         surety, Seguros del Estado ("Seguros"). Wintech started the instant
         lottery in Colombia, but, due to difficulties beyond its control,
         including, among other factors, social and political unrest in
         Colombia, frequently interrupted telephone service and power outages,
         and competition from another lottery being operated in a province of
         Colombia in violation of Wintech's exclusive license from Ecosalud,
         the projected sales level was not met for the year ended June 1993. On
         July 1, 1993, Ecosalud adopted resolutions declaring, among other
         things, that the contract was in default and asserted various claims
         for compensation and penalties against Wintech, SGI and other
         shareholders of Wintech. As the Company has previously disclosed in
         its filings with the Commission, litigation is pending in Colombia
         concerning various claims among Ecosalud, Wintech and SGI, relating to
         the termination of the contracts with Ecosalud (the "Colombian
         Litigation"). Ecosalud's claims in the Colombian Litigation were for,
         among other things, realization on the full amount of the penalty,
         plus interest and costs of the bond.

         SGI has consulted with Colombian counsel and been advised that SGI has
         various legal defenses to Ecosalud's claims. SGI also has certain
         cross indemnities and undertakings from the two other privately held
         shareholders of Wintech for their respective shares of any liability
         to Ecosalud. That obligation is secured in part by a $1.5 million
         confirmed letter of credit in favor of SGI.

         The Colombian surety, which issued a $4.0 million bond to Ecosalud
         under the contract, paid $2.4 to Ecosalud under the bond, and made
         demand upon SGI for that amount under the indemnity agreement entered
         into by the surety and SGI. SGI declined to make or authorize any such
         payment and notified the surety that any payment in response to
         Ecosalud's demand on the bond was at the surety's risk. No assurance
         can be given that the other shareholders of Wintech will, or have
         sufficient assets to, honor their indemnity undertakings to SGI when
         the claims by Ecosalud against SGI and Wintech are finally resolved,
         in the event such claims result in any final liability.

         On April 2, 1998, Seguros brought suit against SGI in the United
         States District Court for the Northern District of Georgia, Atlanta
         Division, Civil Action No. 1:98-CV-968-CAM. The plaintiff sought $2.4
         million for sums paid by Seguros to Ecosalud under the surety bond on
         November 1, 1994, plus interest at the Colombian bank rate of


                                       8

Note 3.           Contingencies continued

         interest. SGI filed a motion to dismiss based on the Colombian statute
         of limitations of two years and, alternatively, sought that the case
         be dismissed on other grounds. Seguros filed a motion for summary
         judgment with the Court on May 6, 1998 seeking summary judgment on its
         claim in the amount of $2.4 million, plus interest.

         On September 29, 1999, the District Court issued an order in which it
         denied various motions of SGI, including a motion to dismiss, and
         granted Seguros' motion for summary judgment. On September 29, 1999,
         the District Court also entered judgment for Seguros in the amount of
         $2.4 million or the equivalent in Colombian pesos as of the judgment
         date, plus pre-judgment interest at a rate of 38.76% per annum,
         equivalent to approximately $4.6 million.

         SGI has appealed the matters covered by the District Court's order and
         judgment. SGI has posted an appeal bond in the amount of $7 million
         through its existing bonding arrangements. SGI continues to believe
         that it has meritorious defenses, including that the amount paid by
         Seguros was improperly paid because of the default by Ecosalud of its
         obligations to SGI, which claims remain the subject of separate
         litigation in Colombia.

         In addition to vigorously prosecuting its appeal of the District
         Court's order and judgment, SGI continues to vigorously defend the
         Colombian litigation and has been advised by counsel that SGI has
         various defenses on the merits as well as procedural defenses to the
         litigation (which it has asserted). Nevertheless, it is not possible
         to determine the exact/ultimate outcome of the appeal of the order and
         judgment granted to Seguros or the outcome of any litigation in
         Colombia. While it is not feasible to predict or determine the final
         outcome of these proceedings, management, based on the knowledge of
         the related facts and circumstances, believes that any potential
         losses will not result in a materially adverse effect on the Company's
         financial position, results of operations, liquidity or capital
         resources.


Note 4.           Comprehensive Income

                           Total comprehensive income was $195,000 and $5.8
         million for the three-month and six-month periods ended June 30, 2000
         and $5.4 million and $10.0 million for the three-month and six-month
         periods ended June 30, 1999, respectively.

Note 5.           Credit Facilities

         The Company has two credit facilities, an $80 million revolving credit
         facility with four banks which expires November 30, 2002 and a $25
         million revolving 364-day credit facility with a single bank that
         expires on November 29, 2000. (Refer to the Company's 10-K for the
         year ended December 31, 1999 for a description of the Company's credit
         facilities). Net borrowings under the credit facilities were $28.9
         million at June 30, 2000.

Note 7.           Plant Closure

         On January 28, 2000, the Company announced plans to consolidate its
         printing operations by expanding its Alpharetta, Georgia facility and
         closing its instant ticket printing operation in Gilroy, California.
         The severance and stay incentive plan was announced to the employees
         on January 27, 2000. A total of $309,000 and $2.8 million in closure
         costs were expensed for the quarter and six months ended June 30,
         2000, respectively. The reserve in accrued liabilities was $2.4
         million at June 30, 2000. These costs consisted of severance, stay
         incentives, lease termination and asset write-downs. There are
         approximately 130 employees that will be terminated including both
         production and support employees at the plant. The plant stopped
         printing operations on July 26, 2000 and will cease total operations
         by the end of August 2000. There were $185,000 in charges taken
         against the reserve during the quarter ended June 30, 2000.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
         CONDITION AND RESULTS OF OPERATIONS.

GENERAL

         Our revenues are generated primarily from sales of our products and
services to governmentally operated or sanctioned lotteries worldwide and, to a
lesser extent, non-lottery related entities both in the United States and
worldwide. We categorize our sales into two main segments: (1) Instant Ticket
and Related Services and (2) Systems.

         In the Instant Ticket and Related Services segment, we primarily
supply game design, sales and marketing support, instant ticket manufacturing
and delivery, inventory management and distribution, and retailer telemarketing
and field services to our customers. In addition, this segment includes
promotional instant tickets and pull-tab tickets that we sell to both lottery
and non-lottery customers and prepaid phone cards sold to telecommunications
companies.

         In the Systems segment, we primarily supply transaction processing
software that accommodates instant ticket accounting and validation and on-line
lottery games, point-of-sale terminal hardware which connects to these systems,
central site computers and communication hardware which run these systems, and
ongoing support and maintenance services for these products. This segment also
includes software, hardware and support for sports betting and credit card
processing systems.

         Instant Ticket and Related Services revenues are generally based on a
price per 1,000 tickets delivered or based upon a percentage of the lottery's
sales to the public over a contract period. Systems revenues may be based on a
fixed price for the product or service or based upon a percentage of the
lottery's sales to the public over a contract period.

         For the period January 1, 2000 through June 30, 2000, we have:

-    received an extension on our current Instant Ticket and Related Services
     contracts with the Kentucky Lottery Corporation through September, 2002.

-    been awarded a new three-year contract, with an option for an additional
     three-year extension, to provide Instant Tickets and Related Services to
     the Washington State Lottery.

-    been awarded a new four-year contract, with an option for an additional
     one-year extension, to provide Instant Tickets and Related Services to the
     Colorado Lottery.

-    been awarded a new two-year secondary supply contract, with an option for
     three additional one-year extensions, to provide Instant Tickets and
     Related Services to the Minnesota Lottery.

-    been awarded a new three-year contract, with an option for two additional
     one-year extensions, to provide Instant Tickets and Related Services to
     the West Virginia Lottery.

-    been awarded a new three-year contract, with an option for two additional
     one-year extensions, to provide Instant Tickets and Related Services to
     the South Dakota Lottery.

-    received one-year extensions on our Instant Ticket and Related Services
     contracts with the Illinois, New York and New Mexico Lotteries.



RESULTS OF OPERATIONS

Three-month period ended June 30, 2000 compared to three-month period ended
June 30, 1999.

         Revenues for the three-month period ended June 30, 2000 increased $4.3
million, or 7.6%, over the revenues for the three-month period ended June 30,
1999. The increase was primarily due to increased Instant Tickets and Related
Services revenues of approximately $8.4 million, which represented a 19.1%
increase for the segment. This increase was mostly due to an $6.8 million
increase in sales of international pre-paid telephone cards, which represented
a 185% increase over the same period last year for this product. Partially
offsetting the increase for the period was a $3.9 million decrease in revenues
from the Systems segment due to lower sales of new systems to international
customers. Instant Ticket and Related Services revenues accounted for
approximately 85.3% and 77.1% of our total revenues for the three-month periods
ended June 30, 2000 and 1999, respectively.

         On a comparative basis, gross margin decreased $3.1 million, or 14.3%,
while gross margin as a percentage of revenues decreased to 30.1% from 37.7%
for the three-month periods ended June 30, 2000 and 1999, respectively. The
margin decrease expressed in dollars was primarily due to the decreased sales
volumes in the Systems segment. The percentage margin decline was mainly
attributable to lower equivalent sales prices charged on certain instant ticket
lottery contracts awarded or extended and the decrease in Systems sales, offset
in part by continued efficiency improvements and additional sales of pre-paid
telephone cards. The lower equivalent sales prices were a result of competitive
pricing pressures in the lottery industry.

         Selling, general and administrative (SG&A) expenses decreased
$107,000, or 1.4%, for the three-month period ended June 30, 2000 from the same
period of 1999. SG&A expenses decreased as a percentage of revenues to 12.2%
from 13.3%.

         Depreciation and amortization expense increased for the three-month
period ended June 30, 2000 by $34,000, or 0.7%, over the comparable period of
1999.

         Plant closure costs, including related severance costs, of $309,000
recorded during the current quarter are for the planned closure of our instant
ticket manufacturing facility in Gilroy, California. This closure resulted from
our decision to consolidate U.S. based production in our Alpharetta, Georgia
facility, which is being expanded to accommodate a state-of-the-art printing
press. Once the new press is operational, we


                                      12
<PAGE>   13

believe the facility consolidation and equipment upgrade will produce cost
savings as well as increase our production capabilities.

         Interest income for the three-month period ended June 30, 2000
decreased $14,000, or 7.4%, compared to the three-month period ended June 30,
1999. The decrease was attributable to lower average cash and cash equivalents
balances in the current period than in the same comparable period of 1999.

         Gain/(loss) on foreign currency for the three-month period ended June
30, 2000 resulted in a loss of $14,000 compared with a loss of $174,000 for the
same period in 1999.

         Interest expense for the three-month period ended June 30, 2000
increased $102,000 from the three-month period ended June 30, 1999. The
increase was primarily due to an increase in the average balance outstanding
under one of our credit facilities compared to the prior period.

         The effective income tax rate for the three-month ended June 30, 2000
was 37.0% as compared to 37.1% for the three-month period ended June 30, 1999.

         As a result of the foregoing, net income for the three-month period
ended June 30, 2000 was $3.5 million compared to $5.4 million for the
three-month period ended June 30, 1999. The decrease in net income of $1.9
million was primarily due to the Gilroy closing costs, the decrease in Systems
sales and competitive pricing pressures discussed above. Net income without the
one-time plant closing costs and associated severance costs would have been
$3.7 million.

         Earnings per common share (diluted) for the three-month period ended
June 30, 2000 were $0.30 compared to $0.45 for the comparable period in 1999.
The decrease in earnings per common share was primarily due to the Gilroy
closing costs, the decrease in Systems sales and competitive pricing pressures.
Partially offsetting the decrease was a reduction in the weighted average
number of common equivalent shares outstanding, resulting from our repurchase
of shares of our common stock during 1999. Earnings per common share without
the Gilroy closing costs would have been $.32.




Six-month period ended June 30, 2000 compared to Six-month period ended June
30, 1999.

         Revenues for the six-month period ended June 30, 2000 increased $10.7
million, or 9.8%, over the revenues for the six-month period ended June 30,
1999. The increase was primarily due to increased Instant Tickets and Related
Services revenues of approximately $20.0 million, which represented a 24.0%
increase for the segment. This increase was mostly due to a $15.1 million
increase in sales of international pre-paid telephone cards, which represented
a 228% increase over the same period last year for this product. Partially
offsetting the increase for the period was a $9.2


                                      13
<PAGE>   14

million decrease in revenues from the Systems segment due to lower sales of new
systems to international customers. Instant Ticket and Related Services
revenues accounted for approximately 85.5% and 75.7% of our total revenues for
the three-month periods ended June 30, 2000 and 1999, respectively.

         On a comparative basis, gross margin decreased $2.6 million, or 6.4%,
while gross margin as a percentage of revenues decreased to 31.4% from 36.9%
for the six-month periods ended June 30, 2000 and 1999, respectively. The
margin decrease expressed in dollars was primarily due to the decreased sales
volumes in the Systems segment. The percentage margin decline was mainly
attributable to lower equivalent sales prices charged on certain instant ticket
lottery contracts awarded or extended and the decrease in Systems sales, offset
in part by continued efficiency improvements and additional sales of pre-paid
telephone cards. The lower equivalent sales prices were a result of competitive
pricing pressures in the lottery industry.

         Selling, general and administrative (SG&A) expenses increased $1.7
million, or 11.8%, for the six-month period ended June 30, 2000 over the same
period of 1999. SG&A expenses increased as a percentage of revenues to 13.3%
from 13.1%. The increase was due primarily to severance costs related to a
management re-organization and higher selling, general and administrative
expenses required to support increased sales activity in new and existing
markets, including pre-paid telephone cards.

         Depreciation and amortization expense increased for the six-month
period ended June 30, 2000 by $530,000, or 6.0%, over the comparable period of
1999 due primarily to additional depreciation expenses from capital
expenditures to support the growth in pre-paid telephone demand and for new
Instant Ticket and Related Services operations.

         The Gilroy closure costs of $2.8 million recorded during the year are
for the planned closure of our instant ticket manufacturing facility in Gilroy,
California. This closure resulted from our decision to consolidate U.S. based
production in our Alpharetta, Georgia facility, which is being expanded to
accommodate a state-of-the-art printing press. Once the new press is
operational, we believe the facility consolidation and equipment upgrade will
produce cost savings as well as increase our production capabilities.

         Interest income for the six-month period ended June 30, 2000 increased
$89,000, or 31.9%, compared to the six-month period ended June 30, 1999. The
increase was attributable to higher average cash and cash equivalents balances
in the current period than in the same comparable period of 1999.

         Gain/(loss) on foreign currency for the six-month period ended June
30, 2000 resulted in a loss of $308,000 compared with a gain of $273,000 for
the same period in 1999. The loss primarily resulted from the negative exchange
rate effect of the strengthening U.S. dollar on certain assets denominated in
foreign currency.

         Interest expense for the six-month period ended June 30, 2000
increased $220,000 from the six-month period ended June 30, 1999. The increase
was primarily due to an increase in the average balance


                                      14
<PAGE>   15

outstanding under one of our credit facilities compared to the prior period.

         The effective income tax rate for the six-month ended June 30, 2000
was 36.7% as compared to 37.5% for the six-month period ended June 30, 1999.
The lower effective tax rate was primarily the result of adjustments to tax
liabilities, due to the favorable resolution of certain contingencies.

         As a result of the foregoing, net income for the six-month period
ended June 30, 2000 was $5.6 million compared to $10.4 million for the period
ended June 30, 1999. The decrease in net income of $4.8 million was primarily
due to the one-time plant closing costs, the severance costs, the decrease in
Systems sales and competitive pricing pressures discussed above. Net income
without the one-time plant closing and severance costs would have been $7.8
million.

         Earnings per common share (diluted) for the six-month period ended
June 30, 2000 were $0.49 compared to $0.87 for the comparable period in 1999.
The decrease in earnings per common share was primarily due to the one-time
plant closing costs, the severance costs, the decrease in Systems sales and
competitive pricing pressures. Partially offsetting the decrease was a
reduction in the weighted average number of common equivalent shares
outstanding, resulting from our repurchase of shares of our common stock during
1999. Earnings per common share without the one-time plant closing and
severance costs would have been $.68.


LIQUIDITY AND CAPITAL RESOURCES

         The Company's cash and cash equivalents balance decreased by
approximately $3.5 million during the six-month period ended June 30, 2000.

         For the six-month period ended June 30, 2000, net cash provided by
operating activities increased by $2.6 million to $13.2 million from $10.6
million for the comparable period in 1999. The primary contributions to cash
from operating activities during the period were net income and depreciation
and amortization.

         Net cash used in investing activities for the six-month period ended
June 30, 2000 increased to $21.8 million from $5.8 million for the same period
in the prior year. These investments were mostly in property and equipment for
our Alpharetta, Georgia and Leeds, England operations and primarily related to
consolidation and expansion projects that were begun in 1999 and which will
continue through the fourth quarter of 2000.

         The Company's financing activities generated cash of $5.9 million for
the six-month period ended June 30, 2000 compared to $1.5 million in the
six-month period ended June 30, 1999. As a result of a net increase in
borrowings for anticipated future capital expenditure requirements during the
current quarter, the balance outstanding under one of our credit facilities at
June 30, 2000 was $28.9 million.


                                      15
<PAGE>   16

         While we estimate we will spend over $45 million in capital
expenditures in the current year, we believe that the availability of funds
under our credit facilities, cash flows from operations and our ability to
obtain alternative sources of financing will permit us to fund our operations
and working capital requirements, as well as other potential investments and
business opportunities. In the event we have additional capital requirements
for new business opportunities, we believe we have the ability to obtain the
required capital from the capital markets.
